Notes

The MAXREFDES220# Smart Sensor FeatherWing development board provides an integrated hardware and software solution which allows you to quickly deploy heart rate and SpO2 monitor features into your product design. This board has two chips on it: the MAX30101 and the MAX32664. The MAX30101 chip is a low power optical heart rate monitor chip which has adjustable sample rates and adjustable LED currents. There are three internal LEDs (IR, red, green) on the MAX30101 chip. The HR and SpO2 (pulse-oximeter) default algorithm uses the IR and red LEDs. The MAX32664 is a small, low cost, power optimized micro-controller. The microcontroller is pre-flashed with C code for finger-based pulse rate and SpO2 (pulse-ox) monitoring. The processed data and raw data are accessible via the I2C bus. Bootloader software is included to allow for future algorithms or updates to the algorithm (In-Application Programming/OTA).

The MAXREFDES220 has been tested on the MAX32630FTHR Ev-Kit board and sample host software is below.
